I deeply love Morse's series, and I deeply love Lewis sequel, each in its own different way. They are two extraordinary detective shows, which I strongly recommend.
So I gave Endeavour a try, both with curiosity and with fear that the experience would ruin my memories of the two shows I liked so much.
Also, Shaun Evans is physically very different from John Thaw, so this made me cringe even before the start.
Having said this, I fell for it from the very first episode.
I was surprised to find out that Shaun Evans is a terrific actor, who plays an entirely credible Morse, if not physically, in a seamless psychological continuity which makes you feel the smooth way in which this young Morse would become the older Morse 20 years later, the incipient causticity, the noticeable anger, the budding low-key self-confidence--- This is very skillfully done in the prequel.
Both Thaw and Evans play the magic of giving a sexy twist to an unsexy character, without flashing the sexy card or even circumventing all attempts to look hot.
Allum plays a marvelous D.C. Thursday and the interaction between them, mentor-pupil, is instrumental to explain how this young Morse ends up being that later Morse.
The 60's atmosphere is a plus in the show, very well portrayed and recreated. I'd say that the linking common trait between Morse, Endeavour and Lewis is, yes, their tremendous atmospheric virtue which sets you right on «in that particular place in that particular time».
If you like detective stories, you will not be disappointed at all, and even if you are not a Morse or Lewis fan, you will find this show entertaining, alluring and deeply satisfactory by its own right.
